In addition, the protective device 1 is preferably installed on a wall body or an independent steel column. The protective device 1 can be used for high-temperature protection, dust protection and camera protection.

[0039] In the oxygen blowing stage of the converter smelting, the first camera 2 is used for observing the shape, color and intensity of the converter mouth flame, so that the composition and temperature of the molten steel in the converter can be judged in real time, and the end point of the converter smelting can be judged. In the slag splashing stage of the converter smelting, the first camera 2 is used for observing the slag splashing out of the converter mouth, so that the slag splashing effect can be judged in real time, and the slag splashing and protection effect in the converter smelting can be judged. In the slag tapping stage of the converter smelting, the second camera 3 is used for observing the color, thickness and fluidity of the slag flowing out of the converter mouth, so that the slag tapping process is stable. In addition, the second camera 3 can also be used for observing the erosion of the lining in the converter. In the tapping stage of the converter smelting, the third camera 4 is used for observing the state in the converter, so that the converter mouth overflow can be avoided, and the tapping process is stable.

[0040] The converter smelting monitoring device can automatically switch the cameras according to the tilting angle of the converter, the image picture is quickly and continuously switched during the camera switching process, the position of the converter mouth is continuously and stably tracked, and the steelmaking operator can continuously track the working state of the converter. Through the real-time linkage and quick switching of the three cameras, the converter mouth can be continuously tracked in different stages of the converter smelting, the converter mouth flame, the slag shape and the lining state can be clearly observed, the converter can be observed and tracked in all directions, without dead angle and full range. The situation that the steelmaking operator needs another operator to observe at the converter or the tapping position due to the fact that the steelmaking operator does not directly master the slag shape and the lining state is avoided.
